Basically yes.

True 'Kelly' which is optimal for bankroll growth, says that you resize as your bankroll goes up and down. So technically if you win a wager, your next bet should be slightly larger than the last with the same advantage. But nobody does that. No one is going to resize that frequently. Plus you would be wagering all these odd amounts. So the compromise position is to resize after a certain % bankroll gain or decline. Something like maybe 20-25%.

The year I started off losing 34k, which was 34% of my original 100k bankroll, I probably should have resized somewhere about 20-25k loss level....but I didn't. I really despise the idea of losing 10's of thousands of dollars playing one betting level and resizing and trying to win that back playing half the level. So I didn't 'resize' when I should have....and got lucky. I think if I had hit 40-50k, I would have resized. I did have the advantage at that time that 100k starting bankroll wasn't all my wealth, but it was a significant portion of it at that time.

The other thing is that I am not trying to grow my bankroll so that I can move up in stakes (betting levels) so as to earn even more money. I am done with that. I went through that growing my bankroll period. I am now comfortably bankrolled for the levels that I want to play for a while. Levels that I have identified as fairly well tolerated, which will hopefully allow for some longevity of another 10 years. "Hopefully"...
